Artesian Wells.

Artesian wells number 1,000 in California. Of these 300 are in Santa Clara valley, fifty miles from San Fancisco. Most of them overflow the surface, and the tubes average seven inches in diameter. The local resources of artesian water are now mapped out. Under the valley runs a broad river, coming from the great lakes of the Sierras, 200 miles off. The pressure from 6,000 feet elevation suffices to throw the water above the surface. The depth of the bore runs from 150 to 250 feet. Outside the boundaries of this subterranean river—several miles wide—no depth of boring has struck artesian water. There is reason b) believe that every valley in the

State lias an underground river, leading direct from the same lakes, and lying below the superficial currents that have no direct connection with any elevated reservoirs.
